Medik8's C-Tetra Advanced is a 30ml lipid-soluble vitamin C serum designed for daily use. Its formulation focuses on stability and enhanced penetration, addressing the inherent instability of vitamin C. This lightweight serum is suitable for most skin types, aiming to brighten complexion and improve skin texture.
This advanced formula utilizes tetrahexyldecyl ascorbate, a stable and oil-soluble form of vitamin C. This derivative allows for deeper penetration and sustained release within the skin.
In addition to vitamin C, the formula incorporates other potent antioxidants like vitamin E and black pepper extract to further protect against free radical damage.
The combination of tetrahexyldecyl ascorbate with other antioxidants creates a synergistic effect, maximizing the benefits of each ingredient. This multi-pronged approach targets multiple pathways of skin aging, contributing to a more comprehensive anti-aging strategy. The focus on research and development ensures optimal ingredient efficacy and delivery.
Medik8 has conducted extensive in-house testing to validate the efficacy of C-Tetra Advanced. Studies have shown improvements in skin brightness, texture, and the appearance of fine lines and wrinkles. Apply a few drops to cleansed skin each morning before moisturizing and sunscreen application.

Directions for Use: 1. Cleanse and tone your face. 2. Apply 4 drops of Medik8 C-Tetra Advanced to your face, neck, and décolletage. 3. Gently massage into the skin using upwards circular motions. 4. Allow the serum to absorb fully before applying your regular moisturiser and SPF.

Recommended Frequency: Apply every morning as part of your skincare routine.

Additional Tips: For optimal results, store C-Tetra Advanced in a cool, dark place.
Vitamin C serums can be more effective when used in conjunction with Vitamin A. Consider incorporating a Vitamin A serum into your nighttime routine.
Always use a broad-spectrum SPF during the day, especially when using Vitamin C, to protect your skin from sun damage and maintain the efficacy of the product.
Introduce new products gradually to assess skin tolerance.
A slight tingling sensation upon application can be normal, but if irritation persists, discontinue use and consult a dermatologist.
